Construction of an 8 m diameter gear to drive the rotary table.
Technical details:
Galbiati Group performed machining operations on a large scale spur gear, which was built in a steel structure at 42CrMo4 TF and mainly designed for machine tool applications.
The spur gear consists of two congruent half-rings and of forged, turned and joined components to perform machining operations.
Firstly, the execution cycle included a turning operation followed by gear cutting and drilling.
At the end of the processing cycle, locating keys were applied to the spur gear.
The pictures below show different stages in the manufacture of the spur gear.

Individual gear segments with can be manufactured with identical pitch radius and high-quality ISO-DIN 7 gears with highly specialized machining on a high-precision 5-axis CNC machine tool.
Properly aligned and fitted along the antenna’s elevation frame, these segments make up a pitch diameters greater than 30 m and suitable for elevation actuation of antennas and radiotelescopes larger than 60 m.
In the category “Global Competitiveness” Galbiati Group Srl was nominated “Supplier Star” for the demonstrated ability in working with Siemens VAI MT, for the design and construction of power transmission parts for rolling mills and casting plants; Auer also highlighted as Galbiati Group Srl well-established a good cooperation with Siemens VAI MT “ providing operational flexibility and high quality, all combined with speed and accuracy in delivery, key features that make Galbiati as the best provider for Siemens Vai of components for metallurgic plants. ”
The Galbiati case is still school: following the event of the last July 8th 2011 2011 it was now the venue for the 21 Assiot affiliates whose Galbiati case history was presented, in cooperation with Staufen, on Friday October 28th 2011. Optimization of production and lean production were the issues covered during the event, both on a theoretical and academic point of view thanks to the great presentation of Dott. Giancarlo Oriani, managing director of Staufen Italia, and on a practical one, through the visit to the facility by all Assiot affiliates (mechanical workshop and assembly department).
One of the strategies, which led to excellent results in terms of production optimization and searching for new prospects is the one Galbiati Group introduced in collaboration with RDI, Staufen and Ecipa Lombardia, in a conference which saw the participation of Sebastiano Barisoni. (Il Sole 24 Ore) as moderator and Professor Alberto Portioli from the Milan Institute of Technology, explained the principles of lean production and innovative communication to the public.
Galbiati Group was rewarded from Hatebur, productive leader of mechanical horizontal printers, like best supplier 2010. We receive this important recognition with large pleasure and satisfaction.
“We were glad to present this special award to Galbiati Group S.R.L. in recognition for their merits in mechanical processing.”
Thanks, there is not better manner “to crown” the first work decade together, and get ready to confront the next one.
Galbiati Group designed and manufactured a complete integrated pinion stand mill drive for special alloys milling (silica, tungsten, vanadium, etc.) for an Austrian customer. The plant consists of a reversible mill stand driven by an integrated pinion stand mill drive, equipped with two pinions meshing together on a center distance just less than 1 m and running at 50 rpm. Input shaft is connected by a toothed coupling to two motors in series, with a total power of 2.400 kW at 195 rpm. This provides a transmissible torque of approximately 460.000 Nm with a suitable service factor, or a nominal torque that greatly exceeds 1.000.000 Nm.
